Hi,

Its been bothering me for sometime that i have lost a huge amount of space in my HD

i have a 640gb HD i know that its not really 640gb its some what lesser.. and when i

checked it up all i have is around 596GB where did the other space went?

Sounds normal to me.

The actual formatted capacity of a 640 gig drive is about 596 gigs.

Formatted capacity is about 7% less than advertised capacity.

The numbers the system shows are in binary. The number the sticker shows is in decimal. And at the GB level, the difference (in numbers) is about 7%. But 93GB in binary are still 100 billion bytes.

i was thinking that they where using 1024 count, but oh well i guess i need to make an external HD as storage

You are right, now multiply 1024x1024x1024 to get to GBs, and you will see that it is 7% more in value. So 100GBs in binary would be 107GB in decimal.

It's because you have to live with less if you are a nerd and live in the base 2 world. Those base 10 bullies just kick their excess bits in your face. Ouch!
